well i know i am a newbie but i see you have no responses so ill put my 2 cents in. everyone ive talked to has different successes with different stuff. i personally didnt like jiffy plugs (stayed to moist) rapid rooters took longer to root and grow (personal experience only) rockwool is a hit or miss some are perfect some stayed to moist and got root rot, oasis im just trying and really like it doesnt stay to moist really airy, and i just bought a aerocloner (bubble cloner?) so i will post when i figure it out. hope this helps.
